The JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external metric threads. Specifically configured for metric fine threads with a right-hand orientation, it helps quality teams and machinists quickly confirm whether an M12 x 1 thread meets the specified size. With its NoGo designation, the gauge is used to identify threads that are out of tolerance, preventing undersized or oversized parts from progressing in production.

Crafted for durability, the gauge uses hardened steel to withstand daily use in demanding workshop environments. This construction supports long-lasting accuracy, maintaining reliable measurements over time and resisting wear from repeated inspections.

• Go/No-Go verification for fast conformity checks: Quickly determine whether external threads meet the maximum size spec, helping you spot non-conforming parts before they move downstream.
• Hardened steel for lasting precision: Built to endure frequent handling and tight inspection cycles, preserving accuracy and reducing replacement needs.
• M12 x 1 metric fine, right-hand design: Precisely tailored for this common size and thread form, enabling consistent, repeatable checks in everyday manufacturing and quality control tasks.

Incorporating this gauge into your inspection workflow translates to faster, more reliable quality decisions. It helps minimize rework, prevents incorrect assemblies, and supports consistent results across shifts, giving you confidence that every M12 x 1 thread meets your standards.
